I cant get mine to unlock with 803 Bios ..




Do you have to make shure Three of the four cores read 0 and only one Core is bumped up or down?

Its odd 803 wont enable it for some reason on my Mobo.

My 720 will do 3700mhz on X4cores with Mod bios though ?

Did you do a CMOS clear before Enabling the Fouth core with 0803 Bios.


Ill keep trying with 803,, for some reason it will only work with MOD 0030 Bios on mineATM
